| Zusammenfassung: | To provide a novel water-in-oil emulsified cosmetic composition that speeds up dermal assimilation during application while enhancing the smooth and moist feels after application.SOLUTION: A water-in-oil emulsified cosmetic composition contains a surfactant, a polymer with a structure represented by the formula (1), oil, and water. In the formula (1), R1, R2 and R3 independently represent a hydrogen atom or a C1-4 alkyl group, A is a C2-4 alkylene group, and m and n independently represent 1.0-50, where the polymer has a number average molecular weight of 10,000 or less and an IOB value of 0.4-1.8; and the surfactant has an HLB value of 3.0 or more and 8.0 or less.SELECTED DRAWING: None
